Authorizations

Authorization

string

header

required

Enter your MeshAPI key (rsk_...) — sent as Authorization: Bearer <key>.

Headers

X-Mesh-Version

enum<string>

default:2026-08

Dated version of the API contract to pin this request to. Omit it and the request is served under 2026-08 — the oldest supported version, so an existing integration is never moved by a release. A malformed or unsupported value is rejected with 400 invalid_api_version rather than falling back silently. The version actually served is echoed as X-Mesh-Version on every response, including errors.

Available options:

2026-08

The Responses API uses a flat structure (name/description/parameters at top level) unlike Chat Completions which nests them under a "function" key:

Responses API: {"type": "function", "name": "add", "parameters": {...}} Chat Completions: {"type": "function", "function": {"name": "add", ...}}
